Yeah, mileage. My 1987 El Camino was factory equipped with 305, 200-R4 and 2.41 open differential. Wouldn’t stay in overdrive on the slightest incline…the engine just didn’t have enough torque for that. Changed to 350HO and 3.73 posi, much better performance, mileage not so much loss as you might think.

Dana 44, may or not be open or limited slip. Ratios available are from 3.08 to 5.38. A 1982 would have a 305 and 200-4R and one of several available optional rear gear ratios. A 3.54 is a good ratio for all around street use. Just my opinion. That is what I installed when I changed to the Eaton Tru-trac differential carrier.

Don't forget that if you eliminate computer controls (rudimentary as they are) you will lose torque converter lock-up function unless you either install a manual switch or an aftermarket control kit for the purpose.
